Low-GWP AREP SOFT-OPTIMIZED SYSTEM TEST

1. Introduction:

A R410A 3T split system heat pump (SSZ140361BA / AVPTC313714AA) was selected for the system soft-optimization test of R32 in Intertek (1809 10th St. Suite 400, Plano, TX 75074) for 10 days. The baseline test of R410A was performed in Goodman psychrometric lab in Houston during which, however, compressor discharge pressure was not measured.

2. Details of Test Setup:

a. Description of System

The R410A system selected for the soft-optimized system test of R32 is SSZ140361BA (OD, SN 1201157846) and AVPTC313714AA (ID, SN 1110632843). The nominal specification and baseline configuration is

b. Description of Modifications to System

Since latent enthalpy of R32 is 50% more than R410A, the charge of R32 was initially designed at 132 oz (3.74 kg, 70% of R410A charge) to accomplish the same total capacity as R410A. During the test, the charge was further optimized to 131 oz (3.71 kg) to obtain 7-10 oF subcooling. ID TXV was changed to a 3T TXV and OD piston was changed to 0.049” per the flow rate estimated. Other components in the system stay the same as R410A system.

c. Description of Tests Conducted

Both baseline R410A test in Houston and R32 test in Intertek follow AHRI 210-240 and ASHRAE 37. Unfortunately, since compressor discharge pressure sensor was not installed in the baseline R410A test, there is no compressor discharge pressure data of baseline R410A test. During cyclic tests of both baseline and R32 tests, the indoor fan ECM motor was turned off and simulation fan was used.

3. Results and Conclusions

a. Data Form

Please see data forms of steady state test A/B/C/H1/H3 in the following pages. The R32 properties are based on NIST RefProp 8 in Intertek (Plano, TX)

b. Conclusions

R32 is compatible to the existing R410A system (no change was made to the system except for the size of the orifice and TXV);

R32 charge is 30% lower than R410A; R32 flow rate is 33% lower than R410A for A/B/H1 conditions; R32 capacity is 4% higher than R410A at A condition and 2% higher in B

condition, EER/COP is 1-2% higher for A/B/H1 conditions (Fig. 2); R32 discharge temperature is higher than R410A, the largest change is

15 oF at H1 condition, the highest temperature is 172 oF at A condition (Fig. 3);

R32 condensing pressure is about 10 psi higher than R410A for A/B/H1/H3 conditions; R32 evaporating pressure is a little higher than R410A;
